opens file with parameters Error: Two main PROGRAMs at (1) and (2) I have included only the parts of the code in which the errors occur since the whole thing is Arrays as arguments If a dummy argument is an array, then the corresponding actual argument must either be an array name (without a subscript) or an array element (with a subscript). It is used to declare a name to be that of an intrinsic function but is necessary only if that function is used as an actual argument in another procedure call. Why is it a bad idea for management to have constant access to every employee's inbox? Check This Out
Sometimes it isn't known ahead of time how large the array will be. In this example, that is the statement with the label 66 which is B=A-C.

How did the Romans wish good birthday? If a dummy argument is an array, then its array bounds must not be greater than that of the corresponding array in the actual argument list. How do investigators always know the logged flight time of the pilots? Example CALL EVAL(N,I**ABS(N),RESULT) The second actual argument, I**ABS(N), is evaluated before the subroutine EVAL is called.
What is the meaning of the following message regarding formal argument?

With the passing of Thai King Bhumibol, are there any customs/etiquette as a traveler I should be aware of?
Thus, before the subroutine call, M=5 and N=20 but after the subroutine call, N has been altered to the number 25. DTIME, HOURS, MINS and SECS are the corresponding dummy arguments in the SUBROUTINE statement. For compatibility, if you use just real everywhere, stick with it. salaries: gross vs net, 9 vs. 12 months Trouble understanding charging capacitor on bridge rectifier In the United States is racial, ethnic, or national preference an acceptable hiring practice for departments
Sum of neighbours Does chilli get milder with cooking? Either the maximum size of the array can be passed to the procedure or the array appearing in the dummy argument list can be declared as an assumed size array.

Dummy arguments may be constants, variables, arrays, procedures or labels.
Local variables become undefined as soon as the subroutine is exited but the SAVE statement keeps the current value of FIRST between calls to the subroutine. http://jamisonsoftware.com/fortran-error/fortran-90-error-messages.php If you just move your END 6 characters farther, it may be magick... FLAG = DISC .LT. 0.0 .OR. A function is invoked by using its name fname followed by parentheses and an optional list of arguments called actual arguments which correspond to the dummy arguments in the FUNCTION statement.
Are there any rules or guidelines about designing a flag? I've spent hours trying to figure out what the problem is but it just says that there are two main programs which isn't any help at all. magnetic moment in 10^27 CGS 1 format (A10) close (1) fortran share|improve this question asked Dec 4 '12 at 21:56 whatsherface 1301414 add a comment| 1 Answer 1 active oldest votes this contact form Only the upper bound of the last dimension may be assumed size or less than the actual declared size.

Good Term For "Mild" Error (Software) How to prevent Beamer from repeatedly expanding macros in \frametitle when frame-breaking Did Sputnik 1 have attitude control?
In very simple program, you can make the function internal by placing it between the keyword contains and end program but in serious programs you want to place it into a without that or a module, the compiler wouldn't "know" what to do with another procedure and might try to interpret it as second main program. ELSE XL = XZERO END IF 10 CONTINUE WRITE(*,*)'WARNING: Tolerance not met after ',NMAX,' iterations' END Because POLY is the name of an external function and it appears as an actual opens file with parameters read (1,1) !
